Pepsin is an enzyme found in the stomach.
It breaks proteins down into peptides.
Pepsinogen:
* is an inactive enzyme, so it doesn't digest the cells in the lining of the stomach. * is converted to pepsin by acid in the stomach * is secreted by cells in the lining of the stomach by zymogen (or chief) cells.
Pepsin is an enzyme that breaks down proteins in the stomach. It is secreted as pepsinogen by the chief cells of the gastric glands. Then, once pepsinogen encounters an acidic environment, it changes shape into its active form, pepsin.
Pepsin is active in the stomach. It is an enzyme produced by the stomach to help break down proteins into smaller peptides.

Did pepsin act in absence of HCL?
Pepsin is inactive in the absence of HCl because the acidic environment is necessary to convert pepsinogen into its active form, pepsin. HCl is needed to denature proteins and activate pepsin through a process called autocatalysis.
Why is HCl used to start the pepsin reaction?
HCl creates an acidic environment in the stomach, which activates pepsinogen to convert into its active form, pepsin. Pepsin is an enzyme that helps break down proteins into smaller peptides.
Pepsin lost it function in alkaline pH?
Pepsin is an enzyme that functions optimally in acidic pH environments, such as the stomach. In alkaline pH conditions, pepsin can become denatured or inactivated, leading to a loss of its ability to break down proteins effectively. This is why pepsin is most active in the acidic environment of the stomach, where it helps in digesting proteins.
What is chemical found in the stomach needed to activate pepsinogen to pepsin?
Hydrochloric acid (HCl) is the chemical found in the stomach that is needed to activate pepsinogen to its active form, pepsin. HCl creates an acidic environment in the stomach that enables pepsinogen to undergo a conformational change and become pepsin, which is essential for protein digestion.
Is pepsin a peptidase?
No. Pepsin is an enzyme that breaks down protein to peptides. Peptidase is another enzyme that breaks down peptides to amino acid. http://www.answers.com/topic/pepsin http://www.answers.com/topic/peptidase
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.
What is the difference between pepsin and pepsinogen?
Pepsin is the active form of the enzyme found in the stomach that helps in the breakdown of proteins, while pepsinogen is the inactive precursor form of pepsin that is secreted by the stomach and is activated by acidic conditions to form pepsin.
What organ is associated with pepsin?
The stomach (it digests proteins).
Which organ secrets enzymes that are active at a low pH?
The stomach secretes enzymes such as pepsin that are active at a low pH to help break down proteins in the acidic environment of the stomach.
Why it is so that pepsin enzyme will not act if its active site is occupied by carbohydrate molecules?
The carbohydrate molecule should not get fitted into the pepsin enzyme.
Why would you predict the pepsin would not digest starch?
Because Pepsin is the active form of a protein manufactured in the stomach.
Did pepsin act in absence of HCL?
Pepsin is inactive in the absence of HCl because the acidic environment is necessary to convert pepsinogen into its active form, pepsin. HCl is needed to denature proteins and activate pepsin through a process called autocatalysis.
Why can pepsin not be produced in its active form?
Pepsin is initially secreted as an inactive precursor called pepsinogen to prevent auto-digestion of the cells that produce it. Once pepsinogen is released into the acidic environment of the stomach, it is activated by hydrochloric acid to form pepsin, which can then break down proteins. This activation process ensures that pepsin only becomes active when it is in the stomach and ready to perform its digestive function.
In which Organ of the digestive system does pepsin works?
Breaks down the proteins into peptide chains
What will happen if body just makes fully active form of enzymes?
Consider the stomach. The inactive form of the digestive enzyme pepsin is called pepsinogin. ( spelling may be wrong ) It takes the release of hydrochloric acid in the stomach to activate this pre-enzyme into pepsin, the active form. You would be digesting your own stomach tissue if pepsin was always active.
Explain the effect of pH on pepsin in terms of the active site of the enzyme?
nothing
Does hydrochloric acid produced in the stomach destroy pepsin?
No quite the opposite the low pH allows the autocleavage of pepsins zymogen pepsinogen into the active form pepsin.
